Humiseal 2A64 Polyurethane Conformal Coating Part A / B

HumiSeal 2A64 is characterized by high solids and low viscosity for ease of application and processing, and it fluoresces under UV light for inspection purposes. HumiSeal 2A64 coating is MIL-I-46058C qualified, and IPC-CC-830 and RoHS Directive 2011/65/EC compliant.

HumiSeal 2A64 conformal coating is:

• Urethane chemistry
• chemically resistant
• two component
• used in combination with Thinner 64

HumiSeal 2A64 conformal coating has:

• excellent moisture and environmental protection for printed circuit assemblies
• fluorescence under UV light for ease of inspection
• MIL-I-46058C qualified
• IPC-CC-830 compliant
• RoHS directive 2015/863/EU

Application of 2A64 Conformal Coating

Conformal coatings can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue “no clean” materials.  Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level.  Please contact HumiSeal for additional information.

Mixing ratio of Part A to Part B is 1:1 by volume. Prior to application, HumiSeal 2A64 Parts A and B should be thoroughly mixed until a homogenous blend is achieved. Vigorous mixing is not recommended. The mixed coating should be allowed to settle for 30 minutes prior to use so that any air bubbles formed during blending can escape.
